RAILRQAID-TBACK-WEEDING MACHINE.

Application filed July 31, 1923. Serial No. 654,939.

To all whom it may concern:

Be it known that I, Anousrn SCHEU cnznn, citizen of Switzerland, residing at Renens, near Lausanne, Switzerland, have invented certain new and useful Improvements in Railroad-Track-Weeding Machines, of which the following is a specification.

This invention relates to machines for removing weeds from railway tracks of the type in a which a tool blade is carried by a truck running along the rails and progectlng therefrom into the road between the individual rail tracks or the road on the outside edge of the rail track so as to remove the weeds by a hoeing action.

In the improved apparatus constructed in accordance with this invention, the tool is carried by an arm which is capable of movement about a vertical axis so that the tool can move clear of obstructions which it may encounter.

In the accompanying drawings which represent one embodiment of the present invention and in which only sufficient detail shown to enable the invention to be understood,

Fig. 1 represents an end elevation of the apparatus.

Fig. 2- is a front elevation of the part shown in Fig. 1, and

Fig. 3 is a plan view to enlarged scale showing the tool in its operative and inoperative positions.

A slide a formed of channel sections back to back is transversely adjustable between rollers 6 5 carried by the frame of the truck. The slide is transversely adjusted by means of a hand lever 7 carried on the platform (Z of the truck and provided with suitable stop notches. This hand lever is connected by a link 6 to an arm 6 pivoted about a pin 0 on the platform the arm e being connected to the slide a by a link 6 The end of the slide a carries a vertical bearing in which a spindle g is axially and pivotally movable. The axial movement is effected by means of a cable It carried by a hoisting pillar The lower end of the spindle g'has pivoted to it an arm through which passes the vertical spindle of the tool blade 76. The upper end of this spindle carries a forked lever 70 to which is attached a cable la which passes round a pulley is? housed in the arm 9 T he end of this cable 70 is connected to a spring 76* which is strong enough to provide the necessary resistance to traction of the tool through the bed but which will yield when any movable obstacle is encountered and will thus enable the parts to swing over to the position shown in dotted lines in Fig. 3. 'The arm is supported by a cable Z which is connected to the crank arm '9 of a crank lever g pivoted upon a collar gtcarried by the spindle g, the crank lever 9 can be adjustedto vary the angle of the tool blade to the horizontal.

I claim: I i

1. In a railroad-track weeding machine and in combination a truck, a transverse slide provided thereon and extending sideways to the outside of the truck, a vertical spindle mounted rotatably at the end of said slide, an arm hinged to the lower end of this spindle, a crank-levercarrying a tool blade and adapted to swing in a horizontal plane at the end of this arm and means for eX- erting a resilient forward pull on said crank lever, so as to cause the blade to attack the ballast substantially. as shown and described.

2. In a railroad-track weeding machine and in combination a truck, a transverse slide provided thereon and extending sideways to the outside of the truck, a vertical spindle mounted rotatably and slidably in an axial sense at the end of said slide, an arm hinged to the lower end of said spindle and carrying the tool blade at its free end, means for lifting this arm to a certain. amount by hand, a hoisting pillar arranged on said slide, and means for hoisting said spindle on said pillar, so as to bring said tool into a position of rest, all for the purpose set forth and substantially as shown and described.

In testimony whereof I aflix my signature.

AUGUSTE SCHEUCHZER.
